ContentIndex: delete() method

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

Note: This feature is available in Web Workers.

The delete() method of the ContentIndex interface unregisters an item from the currently indexed content.

Note: Calling delete() only affects the index. It does not delete anything from the Cache.

Syntax

js
delete(id)

Parameters

id

The unique identifier of the indexed content you want the ContentIndex object to remove.

Return value

Returns a Promise that resolves with undefined.

Exceptions

No exceptions are thrown.

Examples

Below is an asynchronous function, that removes an item from the content index. We receive a reference to the current ServiceWorkerRegistration, which allows us to access the index property and thus access the delete method.

js
async function unregisterContent(article) {
  // reference registration
  const registration = await navigator.serviceWorker.ready;

  // feature detect Content Index
  if (!registration.index) return;

  // unregister content from index
  await registration.index.delete(article.id);
}

The delete method can also be used within the service worker scope.

js
self.registration.index.delete("my-id");
